Abstract:

The newly emerging perovskite solar cells (PSCs) embody excellent properties that are making them an attractive in photovoltaic (PV) technology. However, some shortcomings are impeding their commercial success. These include stability, efficiency, shelf life and operational life time. In this study, we attempted to overcome these shortcomings by exploring the fabrication by a modified spin coating approach where the dispensing of anti-solvent was optimized. Using Methyl Ammonium Formamidinium Lead Iodide as light harvester, several PSC devices were fabricated. For comparison, similar devices were also synthesized using a commonly used standard procedure. The devices were characterized for their I-V and P-V response using full sun solar simulator. Our results revealed that the fabrication approach based on optimized dispensing of anti-solvent resulted in considerable improvements in the efficiency with low production cost. In future, the approach can be adopted to overcome some of the problems associated with the current PSCs fabrication approaches.
